Interface Connecting point in a technical system that has particular properties enabling connection to another technical system.

Leakage current Leakage current is the current that flows via the functional insulation of a consumable to earth or an external conductive part. It can appear as a pure active current or as an active current with a capacitive value. In VDE 0700-1 “Household and Similar Electrical Appliances – Safety”, the following leakage currents are specified:

Internet Worldwide virtual data network.

• For devices of protection class 0 and 0I 0.5 mA • For portable devices of protection class I 0.75 mA

Intrinsically safe Electrical installation that is, in its own right, safe from the point of view of risk of explosion, i. e. no ignitable sparks can occur in the installa- tion. All parts, including the cables, should be blue (RAL 5015) – e. g. at Lapp ÖLFLEX ® EB, ÖLFLEX ® EB CY, UNITRONIC ® EB CY). IP Code A system of designations used to indicate the degree of protection provided by a housing against access to hazardous components, ingress of solid foreign bodies and/or water and to provide additional information relating to this protection (e. g. EN 602529). ISDN Abbreviation for Integrated Services Digital Network. Integrated ser- vice digital telecommunications network. Suitable for transmission of voice, text, images and data. ISO Abbreviation for International Organisation for Standardisation. Commit- tee that develops internationally recognised standards.

• For non-portable motorised equipment of protection class I 3.5 mA • For non-portable heating equipment of protection class I 0.75 mA or 0.75 mA/kW, max. 5 mA

• For devices of protection class II 0.25 mA • For devices of protection class III 0.5 mA

When taking leakage currents for an entire system (also important for residual current protective equipment) into consideration, both the leakage current (residual current) of the cables and the leakage current of the consumable must be accounted for. Length of lay, length of twist The twist length is the distance (measured in the direction of the lon- gitudinal axis) covered by the elements of a layer after being twisted by 360°, e. g. 40 mm. It is usual to specify the number of twists per metre, e. g. 40 mm = 25 twists. Lever series To lock the EPIC ® rectangular connector, there are single or central levers available for the one-handed locking of upper and lower housing sections, the double levers are used for the two-hand locking. Li5YCY TEFLON ® PTFE screened individual cores. TEFLON ® is a brand name of the company DuPont de Nemours. Lift cable Lift cables are control cables with strain relief used for lifts, gantry cranes, teach pads, etc. (e. g. ÖLFLEX ® LIFT, ÖLFLEX ® CRANE at Lapp). Link A link represents a complete section of cabling from the floor distribu- tion board to the data terminal input. It includes all connecting sockets and plugs, installation cables and patch cables. The quality of a link is defined using classes, the quality of the individual components using categories. LiY Individual cores (strand) predominantly 0.14 and 0.25 mm 2 LiYv: Tin plated individual cores (strand). Li2YCY Polyethylene screened individual cores.

J Joint Interconnection point between (data) transmission paths.

The cable has been forcefully bend over a sharp edge, causing plastic deformation of the individual strands and wires. This results in grooves that promote breakages on the individual wires.

kV Abbreviation for Kilovolts. 1 kilovolt equals 1,000 Volts.

L LAN Abbreviation for Local Area Network. Physically limited network used for communication within a building or company. Laser-printer, ink-jet printer With this method, small production batches can be printed at low cost as there is no need for a print wheel to be made. The downside, how- ever, is that it produces a print result of lesser quality. Laying temperature When installed, the cable temperature should not be below +3 °C. Cables with sheathing and insulation are sensitive to bending and impacts when exposed to cold. Leading protective ground The PE contact in a plug establishes the first contact and is the last to disconnect, and is marked as the protective earth symbol.

LiYCY Individual cores with copper screening (C stands for copper).

LiYY Multi-core stranded cable (ÖLFLEX ® , UNITRONIC ® ).

Longitudinal water tightness Achieved by filling the gaps between the core arrangements with vari- ous kinds of filler (e. g. petroleum jelly filling).
